Abstract
A filter device with a preferably hollow-cylindrical, pleated filter element which is arranged concentrically around a cylinder axis and through which a medium to be filtered passes. Seals are necessary on the filter device so that the medium to be filtered will not be able to leak out and so that the filter element, which typically is constructed of filter paper, must be fixed in place together with its pleats. Advantageously, an elastic composition can be disposed as a seal on at least one of the ends of the filter element, and after curing the elastic composition will fix the pleats of the filter element and will have sufficient residual elasticity to seal the filter element with respect to a central mounting tube on which it is to be mounted.
